Mild gasification of coal

, 1989
The objective of this initial year's mission-oriented multi-year program is to develop a process chemistry data base for the mild gasification of coal with emphasis on eastern bituminous coal. One important objective of this program was to obtain the trends in product formation from different coals as a function of several process variables which ...
